Airtac JSI Series Standard Cylinder JSI50X60
The AirTAC Airtac JSI Series Standard Cylinder JSI50X60 is a genuine double acting JIS-standard air cylinder with a Ø50mm bore and 60mm stroke, G1/4 air ports and adjustable end cushioning. Its no-tie-rod, hard-anodized profile barrel is more compact than an ISO 15552 cylinder of the same bore — a space-saver on tight machines.

About the Airtac JSI Series Standard Cylinder JSI50X60
Delivering 982 N of push force at 0.5 MPa, the AirTAC JSI50X60 is a double-acting JIS-standard profile cylinder built for tight machinery layouts. Its extruded hard-anodized aluminum barrel omits external rods, making the unit shorter and more compact than an ISO 15552 cylinder of the same 50 mm bore. The internal two-way piston seal retains grease for low-friction service over a long life.
With a 60 mm stroke, this model is well suited to light positioning tasks. Plan for roughly 589 N of real work at 0.5 MPa, which translates to lifting about 50 kg vertically with a 2:1 safety margin. Pneumatic connections use a G1/4 port. Note that this specific SKU lacks the -S magnet, so it cannot accept CMSE or DMSE position sensors.

Where the Airtac JSI Series Standard Cylinder JSI50X60 Is Used
Package Diverting
Pushes light cartons off a sorting line using its 60 mm stroke and 982 N push force at 0.5 MPa.
Small Part Clamping
Secures plastic housings during a machining operation, safely holding loads under the 50 kg vertical limit.
Flap Folding
Folds corrugated box flaps on an automated packer, fitting easily into compact machine frames.
Is the Airtac JSI Series Standard Cylinder JSI50X60 the Right Cylinder?
When sizing this 50 mm bore, verify your actual load against the 982 N push rating. If your application requires less force, the smaller JSI40 bore provides 628 N at 0.5 MPa; for heavier demands, stepping up to the JSI63 yields 1559 N. Because this 60 mm stroke is short, side-load stress on the rod is minimal.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the end cushions only decelerate the piston and do not act as a brake. To hold a vertical load securely, install an external rod lock or a pilot-operated check valve. If you need position feedback, select the -S magnet variant to enable switch mounting.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac JSI Series Standard Cylinder JSI50X60 FAQ
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa it provides 1374 N push and 1154 N pull. The theoretical maximum force is 200 kgf at 1.0 MPa. The air port size is G1/4.
The JSI is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same 50 mm bore. It uses an extruded aluminum barrel without external rods to save space on machinery.
